upon the axle 12 between the side bars 1 and 2, the axle 12 being mounted inthe bearings 8 and 9 and 8 and 9. The hubs 13 and 14 of the wheels 10 and 11 butt together so as to hold the rims of the wheels spaced apart. A bevel gear 15 issecured to the inner face of the rim of the wheel 10.`

A tongue 16 is mounted between the straps 6 and 7 and 4 and' 5 and centrally between the rear ends of theside bars 1 and 2 and is secured in place by bolts 17 and 18 and the tongue 16 extends backwardly from the main frame a considerable distance. A steering post bearing 19 is fixed upon the rear end of the tongue 16, a steering post 20 is mounted in the bearing 19, a vhand-lever 21 is fixed upon the upper end of the steering post, and a caster wheel fork 22 extends downwardly from the lower end of the steering post 20 and carries a caster wheel 23. An evener 24 is mounted upon the rear end of the tongue 16 and connected to the tongue by. a clevis and pin 25. Swingletrees 26 and 27 are eonnectedto the ends of the evener.

the evener 24. A seotor`29 is mounted upon the tongue 16 directly in front of the platform 28 and a sector hand-lever 30 extends upwardly from the sector, so that the operatorstanding uponthe` platform 28 may manipulate the hand-lever 21 to guide the harvester and manipulate the sector hand lever 30 to control the operating mechanism.

The extension frame comprises side bars 31 and 32 extending forwardly and downwardly from the forward ends of the side bars 1 and 2, a block 33 connecting the intermediate portions of the extension side bars 31 and 32, and the cross bar 34 connecting the extreme forward ends of the extension side bars 31 and 32 and extending some distance both ways beyond said side bars.

Caster wheels 35 and 36 support the ends of theV cross bar 34. The caster wheels`35 and 36 serve to support the harvesting mechanism vand to hold the main frame from tipping sidewise, said caster wheels being a considerable distance apart.

The bearing 37 is mounted upon the shaft An operators platform 28 is built upon the tongue 16 directly in front of support 3 and therear end section 38 of the shaft is mounted in this bearing. A bevel pinion 39 is mounted upon the rear end of the section 38. and meshes with Athe bevel gear 15 so that as the harvester advances.Y

with the wheel. 10 running upon the ground the pinion39 is driven. The intermediate shaft section 40 is connected to the rear section 38 and the forward section 41. is connected to the forward end of the section 40 so as to make a flexible and extensible shaft of three pieces having two universal joints 42 and 43. The ends ofthe shaft section 40 are squared vand slidingly mounted in the sockets. ofthe joints 42' and 43 so asl to make the'shaft e'xtensible'and. contractible as required in tilting` the platform 67.

A bearing` block 44 vis secured at the center of the'front face of the cross bar 34. A bearing 45 extends forwardly from the bearing block 44. A supporting-plate 46 has bearings. 47'and 48 extending downwardly upon opposite sides of the .bearing 45, said bearings 45, 47 and48 beingxconnected by a pin 49. A postfO extends upwardly from the supporting plate 46. mi. v

A circular base 51 is mounted upon the post 50., the post extending through the center of the base, and hinges 52 and 53. connect the base 51 to the cross lbar 34, said hinges 52 and 53 'being in trans-verse alinement with the hinge pin 49 so that the base 51 will rock back and forth on an axis parallelI with the cross bar 34. ta-bly mounted` upon the post 50 above the base 51. 'A web 55 extends from the hub 54. A ring 56 fits against the edge of the webi and. overlaps the side of the web and is secured iny place by bolts 57. A bevel gear 58 is formed upon the lower side of the ring 56 and a spur gear 59. is formed upon the outer periphery of the ring. The bevel pinion 60A upon the forward end of the shaft meshes with the bevel gear 58 so that the rotation of the shaft drives the bevel gear. An annularplate 61 is placed on top of the ring 56 and extends a considerable distance inwardly and outwardly from said ring and is secured in place by the bolts 57 and bolts 62'. The. webl 55 extends from the lower end of the hub 54 and a flange 63 extends from the uipper end of the hub. Turnbuckle rods 64 connect the flange 63 to the inner edge of the plate 61 so as to hold the plate from sagging. An idler gear 65` is mounted upon Va stub. shaft G6` fixed through the plate 61 and the idler meshes with the spur gear-59. The platform 67 is mounted upon the post 50 above the hub 54 and ex! tends a considerable distance beyond the periphery of the spur gear 59. Braces V68 are rigidly secured to the base 5-1 and extend outwardly and upwardly vand are secured to the periphery of the-'platform G7 so as to A- hub 54 is rota-v support the platform 67 upon the base 51. A bearing 69 is secured to the lower face of the platform 67 near its edge, a shaft 70 is mounted through the bearing, a spur gear 71' is fixed upon the lower end of the shaft in mesh with the idler 65, and a belt wheel 72 is fixed upon the upper end of the shaft so that as the gear 59V rotates the wheel 72 is rotated.. A stub shaft 73 is fixed through the platform 67 near its center and a second belt wheel 74 is rotatably mounted upon this `stub shaft. A discharging rake belt 75 v runs' around the wheels 72 and 74 and carries rake teeth 76. The discharging rake belt 75 runs back and forth radially across the platform 67 in position to discharge the beans from the platform. Concentric slots 77, 78 and 79 are formed through the plat-V mounted upon the shaft 86, one end of the spring being connected to a bearing 84 and the other end to a tooth 83 and the teeth 83 extend upwardly through the slot 479 a considerable distance so that as the plate 61 rotates, the teeth extend upwardly through the slot from the beginning' of the slot in front of the discharging rake belt 75l around to .the end of the slot and then at the end of the slot the teeth strike a. wear plate 89 secured to the lower face of the platform 67 and the teeth swing downwardly and pass under. this plate 89 until Vthey come to the beginning. of the slot again. In a like manner the teeth 81 and 82 are mounted to operate in the slots -77 and 78. v The piling rake 90 comprises a head 91 pivotallyv connected t0 the upper end of the post 56- by a pin arms 93. and 94 .extending diametrically through the head 91, and teeth 95 and 96 extending from the arms. The arms 93 and 94 are inI al plane perpendicular to the platform but standY at angles of about thirtyv degrees relative to each other 'in side elevation., as shown in Fig. 2, so that when the arm 94 is down parallel with the platform 67 the. arm 93 is up and vice versa. A segmental slot 97 is formed through thev platform 67 concentric with the post 59. stud 98 has-a shoulder99 and the stud is inserted downwardly through the web .55 until the shoulder strikes the web,`

and a Vnut 190 is placed upon the lower end of the: stud below' the web. The upper end of the stud 98 is beveled to form a cam Y 101said cam being in verticalalinement with theslot97. A cam arm 102 is 'fixed to the rake arm n 94 and, Vextends downwardly." through the slot 97. A cam 103 extends `outwardly and upwardly from the lower end of the cam arm, 102 in position to be engaged by the Y canr101 and a bearing plate 104 extends horizontally from the lower end of the cam 103a so that as the web rota-tes the cam 101 will strike the cam 103 and press the arm 94 upwardly to swing the arm 93 downwardly and the bearing plate 104 will ride over the cam 101 and hold the arm 94 upwardly during the time that the cam 101 is in contact with the bearing plate. A retractile coil spring 105 connects the arm 94 to the platform 67 so that the arm94 is wihdrawn to its normal horizontal position as soon as the cam 101 passes beyond the plate 104. The space 106 upon the platform 67 behind the ,discharging rakebelt 75 issmooth to the ends of the slots 77, 78 and 79 andthe piling rake 90 lis arranged across the platform 67 so that the arm 94 is atrthe opposite side of the space-106 from the discharging rake belt 75.w jThe piling rakes stand at an angle of about thirty dc-V grees relative to the cross bar 34 and the space 106 extends about equal distances each v side of the cross bar.

Supporting arms 107 and 108 are secured at their rear 'ends to the bottom of the base 51 and extend forwardly and downwardly and the frame bars 109 and 110 extend horithe shaft.

zontallyand forwardly from the lower ends,

of these supporting bars. Posts 111 and 112 extend upwardly from the forward ends of the frame bars 109 andv 1 10 and" bearings 113V and 114 are fixed upon the upper ends of the posts 110 and 111. ',A shaft 115 is mounted in the bearings 113 and l114 ,and an apron roller 116 isxed upon the shaft 11.5. Posts 117 and 118 extend upwardly from the frame bars 109 and 110 near their rear ends. Bearings 119 and 120 are fixed to thel upper "ends of the posts. A shaft 121 is mounted Vin' these bearings.A 1-19 and 120 and a second apron roller 122 is fixed upon rollers 116 and 1.12 and carries teeth 124. Braces 125 and 126 connecti the upper ends ofthe posts 111 and 1112 to bearings 127y and 128 upon the outer ends of' the shaft 121 and braces 129 and 130 connect VJthe bearingsY 127 and r128 tothe upper ends of the adjacent Vbraces68 upon theplatform 67. A. bearing An apron 123 runs around the.

block .1314and carriesa belt pulley 138. u A similarvpull'eyv139 is fixed upon the shaft 121 and a. belt 140 runs over the pulleys 138 and 139, so, thatfas the bevel gear 58 operates, the apron 123 is operated, there being a. bevel gear 133 upon the shaft 133 meshingwith a bevel gear 136 upon the/shaft 136. A cross bar 141 connects the rear ends ci. the frame bars 109 and 110'. A bearing 142 is mounted vertically upon `the cross bar 141, aV shaft. 143 is mounted in thebearing, a spur gear 144 is xed upon` the upper end or the shaft, and a bevel gear 145 is formed integral with the spur gear, said bevel gear 1.45 being in mesh with the spur gear 59. A bearing 146 similar to the bearing 142 is fixed upon the crossbar 141,"fa shaft 147 extends through the bearing, and a spur gear 148 is fixed upon the upper end of the shaft 147 :g in mesh with the spur gear 144.

Sprocket wheels 149 and 150 are lixed upon thelower ends of the shafts 143 and 147 below the cross bar'141.. pintle 152 is formed 'upon the lower end of the post 4112 and a similar pintlev is formed upon the lower end of the post 111 and said pintles extendbelow thek frame bars '109 and 110 and sprocket wheels 153 and 154 are mounted upon these pintles. Chain sickles 155 .and 156 are mounted upon the sprocket wheels-,153 and 149, and 154 and 150, respectively, so that as the spur gear 59 rotates the chain sickles 155 .and 156 are driven in the vdirection indicated by the arrows 157 and `158.A The chain sickles 155 and 156 are substantially alikeandare constructed Vas `shown in detail in Fig. 10. 'The short links 159 and 160 are spaced apart by the pivot pins 161 and 162 and the sickle section 163 is placed opposite to the long` link V164. v The sickle section 163 is substantially a right-angled triangle and its long side is ground to make a cut-ting edge 165.

The divider 166 is A-shaped .in plan and its point 167 is adapted to pass 'between two rows of beans and its inolinedsides 168 and 169 are adapted to separate the vines ofV one row from the other and guide the vines backwardly and outwardly toward the siokles 155 and 156. This divider 166 is wedge-shaped in side elevation, as 'seen in Fig, 2, with its lower` side 170 fiat upon the ground and its upper' side 171 inclined npwardly andlhackwardly. At the rear cnd of `the divider'166 are slats 172 formingV aV stationary open apron vin opposition to the travelingapron 123, said apron'172leading over onto. the platform 67.1 The divider 166 and thestationary apron 172 are built together and form a prow and are connected VVto theplatform 67 by beams 173 and 174.

' A cable 175 is connectedto therear end and bottom.v of the base 51k and extends downwardly under a guide pulley 176 on the lll block 33 land then baekwardly under the main frameunder a guide roller ll77l'and is attached to the hand-lever 30, so that by throwing thehand-lever 30 backwardly the cable is pulled downwardly upon the rear end `of the base 51 and will raise'the prow and cutting mechanism from the ground.-

' ln operation, the hand-lever 30 is thrown forwardly andthe prow and cutting mecha'- nism rest upon the ground. The harvesteris to be propelled b'y'hitching draft anima-1ste the swingle-trees 26 and 27 with their heads toward the front of the machine. The operator will guide the machine by manipulating the hand-lever 21 so that the divider 166 vwill pass centrally between two rows of beans and the chain sickles will run upon the surface of the ground or even cut below the surface so as to sever the bean vines completely fromthe ground and the bean' vines will be forced inwardly by the action of the" cha-in sickles and will fall upon the stationary apron 172 and be drawn upwardly and'backwardly by the-action of the movable apron 123. All the gravel, dirt, and foreignv inatter willfall through the slats and the bean vines will be nally discharged from the apron onto the platform 67. As the harvester is moved forwardly the rotation of the wheel 10 will operate the bevel gear 15 to drive the flexible and extensible shaft and drive the bevel gear 58 and rotate 'the plate G1. The spur gear 59 is carried with the bevelvgear w58 and drives the discharge rake belt 7 5. The operationvof' the spur gear 59 also operates the chain sicklesr and the operation of the bevel gear 58 drives the apron 123. As the bean vines pass upon the platform 67 the teeth 81, 82 and 83 carried by the plate 6l will move the vines around upon the platform and pile the vines up against the armA 94 until the cam 103 is operated by the cam 101 to raise said arm 94. Then the pile of beans will pass under the arm 94 to the smooth surface 106 and will be dis-'- charged by the action ofthedischarge rake belt and teeth 7 6. While the arm 94v is elevated the arm 93 is down and the vines are piled up against the armv 93 for an instant and while the arm 93 is down the'teethV tails of construction without departing fromv the spirit of our invention as claimed.
